Nuevos biomarcadores y tomografía de coherencia óptica en el diagnóstico precoz del rechazo agudo y la enfermedad vascular del injerto en el trasplante cardíaco.

Abstract

Se planteo una línea de investigación sobre la utilidad de nuevos biomarcadores y una nueva técnica, la tomografía de coherencia óptica, en el diagnostico del rechazo agudo y la enfermedad vascular del injerto, en pacientes trasplantados cardiacos. Concluimos: 1. Los episodios de rechazo asocian un incremento en los niveles de péptido natriurético B, troponina T de alta sensibilidad y de sST2. Esto puede ser útil en el diagnostico no invasivo del rechazo, ayudando a reducir el número de biopsias y sus costes. 2. Las concentraciones de troponina T de alta sensibilidad se correlacionan con la severidad de la enfermedad vascular del injerto y puede ser útil en la detección de enfermedad vascular severa. 3. La tomografía de coherencia óptica en la evaluación de la enfermedad vascular del injerto muestra una buena correlación con la ecografía intravascular, con la ventaja de una menor variabilidad y mejor caracterización de la placa. Palabras clave: biomarcadores, trasplante, vasculopatía. ENGLISH SUMMARY We propose an investigation to assess the possible utility of new emerging biomarkers and a new imaging technique, the Optical Coherence Tomography, in the early diagnostic of graft dysfunction due to acute cellular rejection or cardiac allograph vasculopathy in heart transplant patients After this investigation we conclude: 1. Acute rejection episodes were associated with marked increments in B-Type Natriuretic Peptide, Highly sensitive troponin T and sST2 levels. This could be useful in the noninvasive diagnosis of acute rejection, helping to reduce the number of programmed endomyocardial biopsies and related costs. 2. Highly sensitive troponin T concentrations correlates with the severity of cardiac allograph vasculopathy and could be useful in the early detection of severe cardiac allograph vasculopathy. 3. Optical coherence tomography in the evaluation of cardiac allograph vasculopathy showed a good correlation with intravascular ultrasound measurements, taking advantage of lower interobserver variability and better plaque characterization. Keywords: biomarkers, transplant, vasculopathy.
